Question

A ladder is leaning against a building forming a 70°angle with the ground. The length of the ladder is 18.3 ft. How far is the base of the ladder from the base of the building? Round your answer to the nearest tenth. (Number part only, do not write commas or units).

Answer 1

Answer: 6.3

Work Shown

cos(angle) = adjacent/hypotenuse

cos(70) = x/18.3

x = 18.3*cos(70)

x = 6.25896862285974

x = 6.3
